ORE-CBUSHER.

Specification of Letters Patent.

Patented Aug. 13, 1912.

Application filed November 23, 1911. Serial No. 661,888.

To all whom it may concern:

Be it known that I, BRUCE WV. TRAYLOR, a citizen of the United States, residing at New York, N. Y., have invented certain new and useful Improvements in Ore-Crushers, of which the following is a specification.

My present invention relates to an improved crusher for crushing ore and other hard materials and has for its object to rovide a crusher having a centrifugal ore feed and at the same time a direct or reciprocating action as distinguished from the gymtory or rotary action of crushers as hereto fore devised with a centrifugal feed.

Other objects are to provide a crusher of this type having multiple crushing jaws, and also to provide various novel features of construction with a view to producing a crusher of great efiiciency, durability and economy.

With these and other objects in view the invention includes the various novel features and combinations of parts as defined by the appended claims.

A crusher constructed in accordance with my invention is illustrated in the accompanying drawings in which:

Figure 1 is a plan view of the crusher, Fig. 2 is a section on line 2-2 of Fig. l, and

' Fig. 3 is a view partly in section, and partly in elevation I Referring by reference characters to these drawings, the numeral 1 designates a feed hopper from which the material to be crushed is fed by gravity into the hollow screw convever which is in the form of a sleeve 2 provided with a spiral rib or ribs 2*, the sleeve being removablv held in the bearing member wherein-after more particularly described- Through this hollow spiral co'nveyer the ore is fed to the space between the two rotating heads 3 and 4 which carry the coacting crushing members or surfaces to which the ore is supplied by the centrifugal action produced by the r0ta tion of the heads. The heads 3 and 4 are rigidly connected together at their outer edges by means of tubular spacing members 5 and bolts 6 and they areprovided with oppositely extending tubular bearing members or sleeves 3 and 4 respectively, journaled in suitable bearings in portions 7" and 7 b of the main frame 7. I secure the centrifugal action referred to by providing a bevel gear 8 fast on the end of member or sleeve 4 with which meshes a bevel gear 8 on a transverse shaft 9 carrying a pulley or other dust from the bearing the parts 4 and 7 near the head 4 may be provided with circumferential interlocking ribs and grooves as indicated at 10. In order to secure the crushing action I provide the annularly arranged opposing crusher plates 11 and 12, preferably of manganese, the former being secured to the face of the inclined portion of the head or member 3, and the latter being secured to the carrier plates 13 which are movable toward and from the plates 11. The connection of the crushing plates may be conveniently effected by means of bolts 11 and 12 having countersunk heads. The carrier plates 13 have their outer edges in pivotal engagement with the head 4 near the outer edge thereof while their inner ends or edges have a pivoted engagement with a collar. or flanged head 14 which head is carried by a longitudinally movable shaft 14, the endwise movement of which rocks the carrier plates 'on their outer bearings, causing the crushing plates 12 toadvance toward and recede from the plates 11 to crush the ore which has been supplied between the plates by the centrifugal action I have found a very advantageous form of pivotal connection to be that shown in the drawings in which the outer ends of the carrier members are provided with rounded projections or ribs 12 resting in corresponding rounded recesses in wear plates 4 carried by the head or member 4; the inner edges or ends of the carrier plates having similar rounded projections or ribs 12 resting in recesses or grooves in the wear plates 14 carried by the collar or flanged head 14,

The carrier plates are held in position by bolts 15 having T heads 15 resting in recesses in the carrier plates, the bolts assing through openings in the head 4 an being supplied with compression springs 15", the pressure of which may be varied by means of the nuts and washers 15 and 15. This construction not only enables ready removal parted from any convenient source.

toggle link 16 has one end 1n plvotal engage ment with a cross head 21 guided in long1- ofthe parts for renewal ofworn crushing plates or like purposes, but provides at the same time, in a very simple and effective manner, for the reciprocation or oscillation of the jaw plates, and holds them firmly in place in their bearings.

The longitudinal movement of the shaft 14 is effected through the medium of togg e links 1.6 and 17 and the interposed pitman 18 operated from an eccentric 19 on the transverse shaft 20 to which power is im- The tudinal ways 22 in the frame, the opposite end of the link being in pivotal engagement with the pitman. The other link has one end in pivotal engagement with the opposite side of the pitman and its other end in pivotal engagement with the frame of the machine as shown, the aforesaid pivotal connections being conveniently efiected by providing the links with rounded ends engaging wear plates having correspondingly rounded recesses. The end of the shaft 1 1 seats rotatably against the cross head, the bearing beother material and from which said material may be removed in any convenient or desirable manner.

The upper halves of the bearing portio 7 and 7 are made removable for insertion and removal of the rotating parts and are provided with lubricating means as shown.

Having thus described my invention what I claim-is: i

1. In an apparatus of the class described a rotary element having an annular crushing surface, an opposing rotary element connected to said first named element to rotate in unison therewith, a plurality of annularly disposed plates carried by said second element and movable toward and from the crushing surface of the first named element as the elements rotate, and means for feeding ore between said crushing elements.
